Synarthonia xanthonica is a species of crustose lichen in order Arthoniales,[1] characterized by its UV-positive orange thallus and linear to ink spot-like ascomata (fruiting bodies). This lichen is corticolous, growing on the bark of trees in primary rainforests in Brazil.
Synarthonia xanthonica was described by André Aptroot in 2022 from specimens collected in the Cristalino nature reserve, Mato Grosso, Brazil. The species was identified as a novel member of the genus Synarthonia. The specific epithet, xanthonica, refers to the presence of xanthone compounds in the lichen, which contribute to the distinctive UV+ (orange) colouration of the thallus.[2]
